Elementary excitations and thermodynamics of zig-zag spin ladders with alternating nearest neighbor exchange interactions

Zvyagin, A.A.; Cheranovskii, V.O. (Физика низких температур, 2009)

The one-dimensional spin-1/2 model, in which the alternation of the exchange interactions between neighboring spins is accompanied by the next-nearest neighbor (NNN) spin exchange (zig-zag spin ladder with the alternation) ...
Energy spectrum and thermodynamics of quasi-one-dimensional ferrimagnets on the basis of transition metal compounds

Cheranovskii, V.O.; Kravchenko, A.A.; Kuznetsova, T.O. (Functional Materials, 2008)

The study of energy spectrum of necklace spin ladder modelling magnetic properties of a number of quasi-one-dimensional ferrimagnetics containing ions of transition metals, was carried out. It was shown that the excitations ...
Validity of t–J approximation for extended Hubbard model with strong repulsion

Cheranovskii, V.O.; Klein, D.J.; Ezerskaya, E.V.; Tokarev, V.V. (Физика низких температур, 2018)

It is shown that for finite cyclic systems described by two band Hubbard Hamiltonian with strong electron repulsion the reduction to effective t–J model may give incorrect description of the ground state symmetry due to ...
Validity of t–J approximation for extended Hubbard model with strong repulsion

Cheranovskii, V.O.; Klein, D.J.; Ezerskaya, E.V.; Tokarev, V.V. (Физика низких температур, 2017)

It is shown that for finite cyclic systems described by two band Hubbard Hamiltonian with strong electron repulsion the reduction to effective t–J model may give incorrect description of the ground state symmetry due to ...
